You know, thinking about it, i don't think i have even seen a self-described "socialist" even bring up theorists or figureheads that they say influenced them. At most, it'll be something like "someone told me they read Chomsky and they gave a quote that sounded pretty good" or "Bernie/AOC/The Squad say some pretty good things and i agree with them". I don't think i've ever seen someone talk about Kautsky or Bernstein or any of the other reformists.
